Grain-elevating machine.



EDMUND H. WESTBROOK AND LOUIS WESTBROOK, OF LIBERTY, MISSISSIPPI.

GRAIN-ELEVATING MACHINE.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed July 10, 1908. Serial No. 442,976.

To all whom it may concern:

Be it known that we, EDMUND H. WEST- BROOK and LoUIs WESTBROOK, residing at Liberty, in the county of Amite and State of Mississippi, have invented certain new and useful Improvements in Grain Elevating Machines, of which the following is a specification.

This invention relates to that class of grain elevating machines wherein the grain is sucked into the machine by air and forced out of the machine by an air blast, and our invention primarily seeks to provide an improved machine of this character wherein means are provided to keep the grain from being broken and damaged by passing through the fan or blower. The means is interposed in the inlet or suction chamber and is adapted to carry the grain across into the outlet chamber so that the grain does not have to pass through the fan or blower.

Our invention is particularly adapted for grain stacking and elevating yet it can be used to move anything that is capable of being moved by air. Our improved device, in operation acts to pick up the material by suction and distribute it by an air blast into bins, boats, rooms, cars or any place desired, and so protecting the material operated upon in its passage from one place to another as not to injure the same in any way by reason of its transfer.

More specifically our invention embodies those novel details of construction, combination and arrangement of parts, all of which will be first described in detail and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which 2- Figure 1, is a central vertical longitudinal section of our machine on the line 11 of Fig. 2. Fig. 2, is a side elevation thereof.

In the drawings in which like letters and numerals of reference indicate like parts in all of the figures, 2 represents an air blast fan or blower whose inlet side is connected with the inlet chamber 1 of the casing 1 of our machine and whose outlet is connected with the outlet chamber 1 of the casing.

3 represents the suction pipe which is connected with the chamber 1 and to which a flexible receiving pipe 3 may be joined so that the funnel end 3 of the pipe 3 may be guided to the material to be transferred.

4 represents the exhaust pipe which is in communication with the chamber 1 and to which a similar transfer pipe of flexible material 4* may be connected, if desired, to transfer and direct the material to its final resting place.

- 5-5 designate sprocket wheels or pulleys over which an endless belt 6 passes, the belt 6 being provided with a series of flights 6 and the belt 6 is perforated at 6 to permit passage of the air, but prevent passage of the material acted upon. The belt 6 passes through openings 1 1 1 and 1 in the easing 1, so as to pass transversely through the passage between the pipe 3 and the chamber 1, and between the pipe 4 and the chamber 1 the casing being off-set as at 1 so that the belt can pass under the same on its return movement.

Flaps 7 of leather, or other suitable material are provided on the casing to prevent the air escaping on the outgoing side to prevent undue air entering the casing on the ingoing side, suitable leaf springs 7 being provided to hold the flaps 7 in their normal position, as indicated in Fig. 1, of the drawings.

A brush 8, mounted with its shaft 8 in brackets 8 serves to clean the belt 6, from any material that may adhere thereto.

The pulley 5 has its shaft 5 mounted in brackets 5 and one of the shafts 5 has a gear 5 over which the endless chain 9 passes. The chain 9 also passes over the sprocket 2 on the drive shaft 2 and over the sprocket 8 on the shaft 8 to drive the belt 6 and the brush 8.

From the foregoing description taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of our invention will be readily understood by those skilled in the art to which the invention appertains.

What we claim is 1. A grain conveying mechanism comprising a body having an inlet chamber and an outlet chamber, and a blower connected therebetween, combined with means for conveying the grain from the inlet to the outlet chamber without passing through theblower, said blower serving to suck air and grain into the inlet chamber and blow the grain out of the outlet chamber.

2. A grain conveying mechanism comprising a body having an inlet chamber and an outlet chamber, a blower connected there-between, combined with an endless carrier passing through said body to carry the grain from the inlet to the outlet chamber, said blower serving to suck air and grain into the inlet chamber and blow the grain out of the outlet chamber.

3. A grain conveying machine comprising a body having an inlet chamber and an outlet chamber, a blower connected there-between, combined with means for separating the grain from the air in the inlet chamber and then conveying said separated grain to the outlet chamber to again mix with the air from the blower.

4. A grain conveying machine comprising a body having an inlet chamber and an outlet chamber, a blower connected therebetween, combined with means for separating the grain from the air in the inlet chamber and then conveying said separated grain to the outlet chamber to again mix with'the air from the blower, said last named means comprising an endless perforated conveyer passing through the inlet and outlet chambers.

5. A grain conveying machine comprising a body having an inlet chamber and an outlet chamber, a blower connected there-between, combined with means for se arating the grain from the air in the inlet 0 amber, and then conveying said separated grain to the outlet chamber to again mix with the air from the blower, said last named means comprising an endless perforated conveyer passing through the inlet and outlet chambers, and means for preventing the escape of air at the places where the belt passes thflough the body, from one chamber to the ot er.
